CDs and DVDs
NOTICE: Always use compressed air to clean the lens in the CD/DVD drive, and follow the instructions that come with
the compressed air. Never touch the lens in the drive.
If you notice problems, such as skipping, with the playback quality of your CDs or DVDs, try cleaning the discs.
1. Hold the disc by its outer edge. You can also touch the inside edge of the center hole.
NOTICE: To prevent damage to the surface, do not wipe in a circular motion around the disc.
2. With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled side) in a straight line from the center to
the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild soap. You can also purchase commercial
products that clean discs and provide some protection from dust, fingerprints, and scratches. Cleaning products for CDs
are safe to use on DVDs.
